To all whom t may concern: n

Be it known that I, PIETRO AIAZZI, citizen of Italy, residing at Winnemucca, in the county of Humboldt land State of Nevada,`

have invented newand useful Improvements in SpikeEXtractors,of which the following is a specification. j 'e Y rIhe present invention relates kto improve- 'ments in'spike eXtractors,fand consists in certain novel features of vconstruction and combination of parts set forth inthe following speciication and kfalling within-the scope of the appended Claim. f A

Onev ofthe primary objects ofthe invention is the construction of a tool for extracting-railroad spikes which shall embody both a claw and co-acting jaws, both of which having a fulcrum member in the nature of a roller which is pivoted between the members of the claw and whereby the spikes may be extractedrapidly and easily withoutin-` jury to the spikes. Y

In the accompanying drawing there has been illustrated a simple andy preferred embodiment of the invention andin said drawing: Figure l is a perspective View of the improved spike` extractor, Fig. 2. is a view illustrating thespike engaged by ,thev claws, Fig. 3 is a similar view illustratingV the spike being withdrawn by the jaws, Fig. 4: isa detail end elevation of the tool looking toward the jaws thereof, and Fig. 5 is a detail sectional view on the line ca -m of Fig. 2.

Referring now to the drawings in detail, the numeral 1 designatesV a lever, of any suitable length, but which/preferably has its lower portion flat and enlarged, as at 2, one

of the edges of the lower portion' being.

rounded toward the second portion, and the rounded edge terminatingl in an enlarged head 3, the said head having both its outerv and inner faces roundedv and projecting beyond the opposite flat sides 2 of the lever.

The numeral 4 designates the combined jaw and claw member ofthe device. The

.member 4 is provided with a head 5 which forms the jaw proper and which is (adapted,

to co-act withthe head or jaw 3 of theV lever l; The head has both of its faces rounded,"

j and also contacts Vwith oneof the edges of' P-ivotally connected, as at `10,y between the rounded corners ofthe claws at'their juncture with thesides proper, and projecting :a

suitable .distance beyond Vsaid corners isa wheel llwhich serves-as a 'fulcrum' for both the claws andthe jaws,as clearly illustrated l in the figures of lthe drawing, f'

From theabove description, taken in connection with the accompanying drawing, the

simplicity of the device as well as the advantages thereofy will, it .is thought, be perfectly apparentto those skilledin the art to if' y which vsuch inventions Vappertain without further 'detailed description.

Having thus A describedl the il invention, `whatIclaim 'isfl A spike extractor comprising a lever, a

jaw prcvidedon the end of vsaid lever, said jaw having a Hat lower surface and a rounded outer face, theinner face of said jaw being inclined at an angle Vto the baseand adapted t abut against the under side lof the headfof the spike'. when the spike is nectedrtoVv the lever,said j aw comprising a bifurcated member fitting over the flat portion of the lever andpivoted thereto, and a Vpartlyl extracted, a second jaw pivotally conjaw member disposi-:tl opposite the 'integral y jaw, said j aw member having an angularly In testimony whereof I aix my signature dsplsed inne face, the bifurcated plrtion np'resence of two witnesses.
